What are the differences between real-time data processing and batch processing?

What are the differences between real-time data processing and batch processing?

Real-time data processing involves continuous input and output of data, allowing immediate insights, while batch processing collects data over a period and processes it all at once.

Can you give me examples of where each is used?

Sure! Real-time processing is used in online transaction processing, like credit card transactions, while batch processing is common in payroll systems.

What are the advantages of real-time processing?

The main advantages include immediate data insights, faster decision-making, and the ability to respond to events as they happen.

Are there any disadvantages to real-time processing?

Yes, it can be more complex to implement, requires more resources, and may lead to higher costs compared to batch processing.

Which one is better for big data applications?

It depends on the use case. Real-time processing is better for applications needing instant insights, while batch processing is suitable for analyzing large datasets periodically.
